Although you may have become very proud and protective of your belly, it can be extremely irritating if other people become overprotective of you. You may find that everyone has an opinion on your pregnancy, and what you should and should not be doing to stay healthy. Some women find all the attention comforting, but others find it frustrating or suffocating. If you're someone who finds all the advice difficult to handle, try to remember that people mean well.
Of course, it's your body, and you'll do what is best for you and your baby. If it's all getting too much, then try talking to the main offenders, often a partner, mother, or mother-in-law. Explain that you're trying your best and that you're aware of what you should and shouldn't do while you're pregnant and are following the advice of your doctors. Politely thank them for their input and reassure them that you're taking good care of yourself and your baby.
